Soft soil foundation comprehensive pipe gallery and construction method thereof

Abstract

The invention relates to a soft soil foundation comprehensive pipe gallery and a construction method thereof. The soft soil foundation comprehensive pipe gallery comprises a pipe gallery body. A plurality of prestressed reinforced concrete pipe piles are arranged at the bottom of the pipe gallery body. All the prestressed reinforced concrete pipe piles are arranged in a soil body at the bottom of the pipe gallery body. The top pile heads of all the prestressed reinforced concrete pipe piles are fixedly connected with a bottom plate of the pipe gallery body. Detachable Larson steel plate piles are arranged in soil bodies on the two sides of the pipe gallery body in the longitudinal direction of the pipe gallery body correspondingly. The Larson steel plate piles and the two sides of the pipe gallery body are arranged in a spaced mode. The Larson steel plate piles form a construction side supporting structure of the pipe gallery body. According to the soft soil foundation comprehensive pipe gallery and the construction method thereof, the large settlement and floating problems of soft soil foundation pipe galleries in the prior art are solved, failure of the comprehensive pipe gallery is avoided, and the stability of the comprehensive pipe gallery is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of urban underground building components, in particular to a comprehensive pipe gallery on soft ground and a construction method thereof. Background technique [0002] The comprehensive utility corridor, also known as the "comprehensive corridor", is an inevitable choice for expanding urban functions and developing a beautifying environment. It has the characteristics of long lines, and different geological conditions must be encountered along the lines. The comprehensive pipe gallery is a one-time foundation pit excavation and construction project, which has strict requirements on the bearing capacity and deformation control (settlement, etc.) of the foundation. The damage caused by the insufficient control of the bearing capacity and deformation of the foundation will be immeasurable. [0003] The requirement of small settlement is one of the difficulties in the construction of the pipe gallery, so the req...
